After their fight, Maria and her sister didn’t talk for a week. Then they sat down to patch things up.

We had some problems with the project, but our team worked together to patch things up before the deadline.

The tent had a hole from last summer. Before the camping trip, we patched it up so it wouldn’t leak.
